Abstract

The invention discloses a water heater outlet pipeline cold water recycling device, comprising a pressure water storage tank, a control module, a hot water inlet pipe, a hot water outlet pipe and an electric three-way valve; wherein the hot water inlet pipe is provided with a temperature sensor, the hot water outlet pipe is provided with a pressure sensor, the temperature sensor, the pressure sensor and the electric three-way valve are respectively electrically connected with the control module, the bottom of the pressure water storage tank is provided with a cold water loop inlet pipe and a cold water loop outlet pipe, a first outlet of the electric three-way valve is connected with the cold water loop inlet pipe, the inlet of the electric three-way valve is connected with the hot water inlet pipe, and a second outlet of the electric three-way valve is connected with the hot water outlet pipe. The invention has the advantages that massive water resource can be effectively saved, structure is simple, the device is not restricted by mounting position when in use, the traditional water supply pipeline system is not required to be changed, thus being applicable to all domestic water heater systems, especially solar water heater, less electricity is consumed, and automation control is realized by virtue of the control module.

Description

technical field [0001] The invention relates to a water heater device, in particular to a cold water reuse device for a water heater outlet pipeline. Background technique [0002] In the implementation rules for the design and implementation of solar water heating systems for civil buildings in some cities, it has been clearly required that residential buildings with 12 floors and below and the reverse 6 floors of residential buildings with more than 12 floors must be designed with solar water heating systems. However, in actual engineering, if the residence is designed as a centralized solar water heating system, there will be problems in later operation and management, and it is difficult to promote; When using water, the cold water in the pipeline must be released first, which will waste a lot of water resources. Taking the penultimate 6th floor as an example, based on the floor height of 2.8m, the pipeline from the water heater to the toilet should be at least 40m, and ...
